Detailed Product Description
Oil and Acid Resistant Pn16 Carbon Steel Flexible Concentric Reducer Rubber Coupling
A concentric but differently sized rubber expansion joint is a flexible compensating element used for connecting
pipes of different diameters. The centerlines of its two flanges coincide (concentric), but the diameters are different
(DN200 to DN150). It compensates for displacement through its rubber body.
Key Features:
  • Good elasticity for vibration and noise reduction
  • SS304 flange connection
  • Single sphere rubber expansion bellows design

Product Description
Rubber expansion joints consist of inner and outer rubber, cord layer and steel wire strand,
which are vulcanized and then combined with metal flanges or loose sleeves of parallel joints.
It is widely used in various pipeline systems.

The rubber expansion joints allow for four way movements, and they are molded from
synthetic rubber and nylon cord. This design reduces vibration and noise, and compensates
thermal expansion and contraction caused by temperature change.
